A 3D Printing Racing Car

While it isn't the world's first 3D printed car, it may be the first 3D printed Racing Car. The Areion was designed by 16 engineers from "Group T" as their entry in the Formula Student 2012 Challenge.

Obviously, the entire car was not 3D printed - only the body, which was then attached to a conventional chassis, engine and other parts. Unlike the Urbee 3D printed car, whose body is composed of a dozen or so 3D printed parts, the Aerion's body appears to be a single piece.
